CHRIS ANDERSON AND I-IUIBERT M. RUDDOCK, OF CALDWELL, IDAHO.

PUMP.

Application filed June 30, 1913.

To all whom it may concern:

Be it known that we, CHRIS ANDERSON and HUBnR'r M. RUDDooK, citizens of the United States, residing at Caldwell, in the county of Canyon and State of Idaho, have,

invented certain new and useful Improvements in Pumps, of which the following is a specification.

The invention relates to improvements in pumps.

The object of the present invention is to improve the construction of pumps, and to provide a simple, eflicient and inexpensive pump of strong and durable construction, designed for elevating water for irrigation and other purposes, and capable of pumping thin mud and other substances, which form obstructions in and prevent the operation of an ordinary pump.

A further object of the invention is to provide a pump of this character equipped with a vertically disposed water elevating wheel, adapted to be submerged in water and which will require neither priming nor oiling.

Another object of the invention is to provide a water pump having a double feed or inlet provided with air chambers adapted to assist the operation of the pump by forcing a heavier stream of water on the elevating I wheel.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion,

size and minor details of construction, withthe transverse partitions and the end walls in the scope of the claims, may be resorted to without departing from. the spirit or sacrificing any of the advantages of the invention.

In the drawings :-Figure 1 is a vertical sectional view of a pump, constructed in accordance with this invention, the section being taken longitudinally of the pump casing. Fig. 2 is an elevation of the lower portion of the pump. Fig. 3 is a central vertical sectional view of the pump, taken at right angles to Fig. 1. Fig. 4c is a horizontal sectional view on the line H of Fig. 1. Fig. 5 is a vertical sectional view on the line 55 of Fig. 1.

spending parts in all the figures of the drawings.

In the accompanying drawings in which is illustrated the preferred embodiment of the invention, 1 designates a horizontal pump casing of substantially cylindrical form, designed to be constructed of any suitable material and mounted within the lower portion of a vertical frame 2 and divided by spaced transverse partitions 3 into a central water wheel compartment 4 and side inlet or air chambers 5. The end walls 6.of the casing are provided with central bearing openings in which is journaled a horizontal longitudinal shaft 7 carrying a vertical water elevating wheel 8. The water elevating wheel 8, which may be variously constructed, is shown in the accompanying drawings as consisting of a sleeve or hub 9, integral radial arms or spokes 10 and blades 11, having inner tapered portions 12. The outer portions of the blades are of a width to extend nearly across the space between the partitions 3, the water elevating wheel fitting snugly within the central chamber 'while being actually out of contact with the walls thereof, so that there will be no friction to interfere with the free rotary movement of the said wheel.

The horizontalcasing is provided at the top of the side compartments with inlet iopenings 13, located adjacent to one of the SlClG walls of the casing and in a line with a vertical discharge conduit 14: extending upwardly from the central wheel receiving compartment. The side compartments are provided at the inner sides of the inlet openings 13 with depending partitions 15, extending entirely across the spaces between of the casing and forming upper air pockets 16, in which air collects and is compressed so as to assist the operation of the pump. The side compartments form a double feed and in practice the casing is submerged in the water, so that the water will be forced by gravity into the side compartments. The transverse partitions are provided with central eyes or openings 17 communicating with the central compartment and permitting water to flow into the same from the side or inlet chambers. The eyes or openings 17 are circular and the blades of the water elevating wheel taper inwardly from points adjacent to the walls of the eyes of openings 17, so that the water is permitted to flow freely through the openings into the spaces between the blades of the wheel.

The discharge outlet 14 is shown rectangular in cross section and of a width equal to that of the central chamber or compartment of the pump casing to facilitate a rapid and easy discharge of water, but the discharge conduit may be constructed in any other desired manner and may be of any other preferred form. The pump casing is provided at the lower end of the discharge conduit with an opening 18 and it has grooves 19 and 20 located at the sides and bottom of F the opening and adapted to receive a slidable closure 21, which affords access to the interior of the central chamber or compartment of the pump casing.

The frame of the pump, which is composed of corner posts and suitable connecting bars, may be of any preferred construction, and it is provided with upper horizontally alined bearings 22 in which is journaled an upper horizontal driving shaft 23. The horizontal driving shaft, which is designed to be provided with suitable operating means, is connected at one end by bevel gears 24 and 25 with the upper end of a vertical shaft 26, journaled in vertically alined bearings 27 of the frame and connected at its lower end with one end of the lower horizontal shaft 7 by bevel gears 28 and 29.

The pump may be driven by any suitable power, and it has been found by experience that a pump having a water elevating wheel of four inches and submerged in water to a depth of approximately two feet will rapidly raise water ten feet when running at approximately three hundred and seventy four revolutions per minute. Pumps, however, of any desired capacity may, of course, be constructed.

What is claimed is 1. A pump of the class described including a horizontal casing comprising side compartments provided at the top with inlet 7 openings and having upper air pockets, and

a central compartment located between the SlCle compartments and communicating centrally thereat, a dlscharge conduit extending from the central compartment, and a vertically disposed rotary water elevating wheel operating within the central compartment.

2. A pump of the class described including a horizontal casing comprising side inlet compartments provided at the top adjacent to one side of the casing with inlet openings and having depending partitions extending downwardly from the inner sides of the openings and forming upper air pockets, and a central compartment having central openings in its opposite walls communicating with the side or inlet compartments, a discharge conduit extending from the central compartment, and a vertically disposed rotary water elevating wheel operating within the central compartment.

3. A pump of the class described including a horizontal casing having spaced partitions dividing the easing into central and side compartments and provided with circular openings, said casing being also pro-' vided at the tops of the side compartments with inlet openings and having air pockets, a horizontal shaft journaled in the casing and extending through the central compartment, a vertically disposed water elevating wheel mounted on the shaft and having blades tapered inwardly at the said opening, and means for rotating the said shaft.

4. A pump of the class described including a frame, a horizontal casing mounted within the frame at the bottom thereof and composed of communicating side and central compartments, the side compartments being provided with inlet openings, a vertical discharge conduit extending upwardly from the said central compartment and having a width substantially coextensive with the same, and a vertically disposed water elevating wheel operating within the central compartment. v

In testimony whereof we aflix our signatures in presence of two witnesses.
